在datagridview上保存数据的按钮代码

Question

I am trying to use this code on vb2010 datagrid to save changes made on the datagrid but the problem is that even when the user clicks save button and they didnt make any changes, the MsgBox("Changes Successfully Effected.") is stil displaying that changes are made. Me.Validate() Me.StudentsBindingSource.EndEdit() Me.TableAdapterManager1.UpdateAll(Me.DataSet) MsgBox("Changes Successfully Effected.", MsgBoxStyle.Information + MsgBoxStyle.OkOnly) How will i fix this?

Put your code in an if condition like below.

IF Me.DataSet.HasChanges() Then
  Me.TableAdapterManager1.UpdateAll(Me.DataSet)
  MsgBox("Changes Successfully Effected.", MsgBoxStyle.Information + MsgBoxStyle.OkOnly)
End If
